So my question is does that mean that it has 105 subscribers from lemm.ee and that count is all I see when entering from this instance?
Unfortunately yes, that's the way it works right now.
I agree it's not really ideal. I believe it can be improved in the future, though.
subscriber count aside, I see more users/day and users/week etc when accessing it from lemm.ee, but the comment count is acutally less even though lemm.ee hasn’t any blocked instances and also isn’t blocked by any other instance.
These numbers can get out of sync when there are any problems with federation. But the same applies here as well - I think this can and will be improved soon!
By the way, I know this isn't a proper solution, but as a workaround I actually prefer using https://lemmyverse.net to browse communities now, because you can set your home instance there and that will automatically link you to any community directly on your home instance!
